FT2232L Dual USB UART / FIFO I.C.  
1.0 Introduction  
The FT2232L is the lead free version of FTDI’s 3rd generation USB UART / FIFO I.C. family. This device features two  
Multi-Purpose UART / FIFO controllers which can be configured individually in several different modes. As well as a  
UART interface, FIFO interface and Bit-Bang IO modes of the 2nd generation FT232BM and FT245BM devices, the  
FT2232L offers a variety of additional new modes of operation, including a Multi-Protocol Synchronous Serial Engine  
interface which is designed specifically for synchronous serial protocols such as JTAG and SPI bus.
